USGA Summary Points:Summer DLIs were measured to be similar between the two years. In year 1 (2016), DLIs produced by the shade treatments were 5.8, 8.6, 11.7, 20.9, 27.9, and 47.6 mol m-2 d-1 for the 90, 80, 70, 50, 30, and 0% (Full Sun) shade treatments, respectively. For year 2 (2017), summer DLIs were 5.4, 8.7, 12, 21.1, 27.9, and 46.2 mol m-2 d-1 for the 90, 80, 70, 50, 30, and 0% (Full Sun) shade treatments, respectively (Table 2). During Summer months, DLIs for Fairway Height turf were highest for bermudagrass cultivars and lowest for zoyiagrass cultivars. Trinexapac-Ethyl reduced DLI requirements by ~0.5 to 2 mol m-2 d-1 in bermudagrasses and by ~3 to 7 mol m-2 d-1 in zoysiagrasses (Figure 1). Without TE, Fairway bermudagrass cultivars ranked as follows, from lowest to highest Summer DLI requirement: Latitude 36 < Celebration < TifGrand < Tifway. With TE, bermudagrass ranked as follows, from lowest to highest Summer DLI requirement: Latitude 36 < TifGrand < Celebration < Tifway (Figure 1). Without TE, Fairway zoyisagrass cultivars ranked as follows, from lowest to highest Summer DLI requirement: Zorro < Zeon < Palisades < Geo < JaMur. With TE, zoysiagrass ranked as follows: Zorro < Zeon < JaMur < Palisades < Geo (Figure 1). At Rough Height, cultivars expressed a much wider range of Summer DLI requirements, from as low as 11.75 to 32 mol m-2 d-1. At Rough Height, Summer DLI ranked as follows for the bermudagrass cultivars: Celebration < Latitude 36 < Tifway < TifGrand. Zoysiagrass cultivars ranked as follows: Zorro < Zeon < Palisades < JaMur (Figure 2). At Rough Height, minimal DLI required for acceptable Turf Quality in Zorro and Zeon zoysiagrass (11.75 and 13.25 mol m-2 d-1, respectively) were lower than that required for Palmetto St. Augustinegrass (15.5 mol m-2 d-1) (Figure 2). Minimal DLI required for acceptable Turf Quality was noticeably lower for all cultivars for the Spring and Fall periods (Data not shown).
